How does the coronavirus disease spread?

April 26, 2020

See full answer COVID-19 is a new disease and we are still learning how it spreads. The virus that causes COVID-19 is thought to mainly spread from close contact (i.e., within about 6 feet) with a person who is currently sick with COVID-19. The virus likely spreads primarily through respiratory droplets produced when an infected person coughs or sneezes, similar to how influenza and other respiratory infections spread. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. This type of spread is not a concern after death. It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.

Is the coronavirus disease new?

COVID-19 is a new disease, caused be a novel (or new) coronavirus that has not previously been seen in humans.

Can the coronavirus disease spread through air?

The virus that causes COVID-19 is mainly transmitted through droplets generated when an infected person coughs, sneezes, or speaks. These droplets are too heavy to hang in the air. They quickly fall on floors or surfaces. You can be infected by breathing in the virus if you are within 1 metre of a person who has COVID-19, or by touching a contaminated surface and then touching your eyes, nose or mouth before washing your hands.

How long does the coronavirus last on surfaces?

Current evidence suggests that novel coronavirus may remain viable for hours to days on surfaces made from a variety of materials. Cleaning of visibly dirty surfaces followed by disinfection is a best practice measure for prevention of COVID-19 and other viral respiratory illnesses in households and community settings.

Is the coronavirus disease the same as SARS?

No. The virus that causes COVID-19 and the one that caused the outbreak of Severe Acute Respiratory Syndrome (SARS) in 2003 are related to each other genetically, but the diseases they cause are quite different.

Can pets spread the coronavirus disease?

In the United States, there is no evidence to suggest that any animals, including pets, livestock, or wildlife, might be a source of COVID-19 infection at this time. However, because all animals can carry germs that can make people sick, it's always a good idea to practice healthy habits around pets and other animals. Wash your hands after handling animals, their food, waste, or supplies. Practice good pet hygiene and clean up after pets properly.
